Fluorocarbon Duel HD Carbon Fune Leader  depending on the section,  has a different degree of rigidity: hard (Hard), semi-hard (Semi-Hard), semi-soft (Semi-Soft). This makes it truly versatile and  allows you to use in any fishing conditions. Thin diameters  have maximum rigidity, due to which less confusion, increased abrasion resistance. On the other hand, medium and thick sections are made softer to increase elasticity.
